Comment 0 for bug 1245185

I tried to setup havan with docker hypervisor on Centos 6.4

I followed this documentation to setup docker: http://nareshv.blogspot.de/2013/09/installing-dockerio-version-061-on.html
I pulled out all other relevant topics regarding docker out of devstack. I have started a docker repository on the same node, it works, images are available in horizon.

When I try to start a new instance with e.g. the centos or busybox docker image it will fail.
When I observe docker (docker ps) then I can see that a instance will be created and after a couple of seconds removed.

In the log file I found following:
